Long story short on way home tonight thought i would put the Snow button on to see what it was like on slippery roads, after driving it for a few miles decided to switch it off again but the car didn't return to normal feels like there is no power what so ever and missing. Was this to do with the snow mode being on or something else. Car has run spot on until i pressed that button tonight.

Is that just to reset the ECU? tried resetting it just now but made no odds. Kinda worried to take it for a run in case i do more damage. Saying that though no warning lights have came on the dash and oil pressures etc seem fine.

Might be a case of checking plugs tomorrow them maybe just bad luck sowts happened when button was on .
